Future of interfacial electrochemistry: from structure-function relationships to better understanding of charge transfer reactions and (photo)electrocatalytic reactivity

Charge transfer modulated heterointerfaces for hydrogen production at all pH values

“…1 The desired advancements in this field necessitate advanced fundamental knowledge of the interfacial reactions, the charge transfer processes, and atomic/molecular level structure–reactivity synergism at the heterointerfaces. 2 The combination of dissimilar chemical compositions or crystal structures creates these interfaces with broken crystal symmetry and an electronic environment, that in turn produces new electronic states by the strong coupling of orbitals, spins and lattices. 3 When the Fermi energy levels are mismatched at these solid–solid heterointerfaces, the phases in contact try to align their Fermi levels by altering the electronic environment through electronic charge transfer.…”

Recent advances on portable photoelectrochemical biosensors for diagnostics

“…PEC sensor is a new type of sensing technology developed based on electrochemical sensors, which passes through the photoelectric conversion ability of photoactive materials under light conditions. Changes in interfacial electron transfer, electrolyte environment, electron donor/acceptor mass transfer and light absorption can be induced according to changes in target concentration [6][7][8]. And then achieve the purpose of monitoring and analysis [9,10].…”
